What this means for your business

- An attacker can use it remotely, over a network, with an administrator login, but only after tricking someone into an action such as opening a file or a link.
What to do
- 1Check whether your company or your suppliers run Adobe Commerce, and which version. The affected versions are listed further down this page.
- 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
